Delete clusters
Use this task to remove a cluster and all of its cluster members.
Removing a cluster deletes the cluster and all associated cluster members. When you delete a cluster, there is no option to keep certain cluster members or applications that we have installed on any part of the cluster.
If the cluster we are removing has applications or modules mapped to it, remap the modules to another cluster, or create a new cluster and remap the modules to the new cluster, before removing the old cluster. After a cluster to which modules are mapped is deleted, the modules cannot be remapped to another cluster. Therefore, if we do not remap the modules to another cluster before deleting the old one, uninstall all of the modules that were mapped to the old cluster, and then reinstall them on a different cluster.
